Hugo Roirand is a research engineer in additive manufacturing at CETIM, where he supports the industrial deployment of AM technologies across the mechanical sector. His mission is to assist companies in adopting and optimizing additive processes. Current projects include the architecture and administration of dedicated materials and AM process database for the nuclear industry, the development of large-scale PBF-LB machines, and technical support for industrial partners working on AM parts. This includes work on refractory materials, microstructural control through process parameters, and beam-shaping techniques to improve productivity and part quality. Hugo is also committed to reducing the environmental impact of additive manufacturing. He contributes to life cycle assessment studies focused on the PBF-LB process, aiming to better understand and minimize the footprint of the entire AM supply chain. Before joining CETIM, Hugo graduated as a materials engineer from ENSIACET in 2019, complemented by a research master’s degree from Paul Sabatier University. His scientific curiosity led him to pursue a multidisciplinary PhD between CIRIMAT, ICA, and I2M, focused on the fatigue behavior of PBF-LB parts. His research aimed to use the PBF-LB process to control microstructure and defect populations, in order to understand their competition in fatigue performance. This research has been showcased at multiple international conferences and resulted in five peer-reviewed publications. This work was followed by a postdoctoral project on hybridation of additive processes for maritime applications. These experiences gave him a strong foundation in metallurgy, mechanical behavior, and the process–microstructure–performance relationship—key elements for supporting industries in qualifying parts and successfully integrating additive manufacturing technologies.
